The Difference

Thoughtful Fabric: Siro Micro Modal is an environmentally friendly, sustainably produced fabric known for being extremely smooth, soft, and cool to the touch. The fabric is resistant to shrinkage, fading, and hard water deposits (so it stays soft). It’s also extremely breathable, excellent at absorbing moisture, and shows minimal pilling. The 5% spandex allows freedom of movement without bunching.

Intelligent Design: We took special care to create a boyshort with no center seams because we know what does (and doesn't) feel good on a woman's body.
